kayak-tour in Marocco april 2013

Hi; Is there anyone, who can give me some information about the water-levels and the dangering aspects in relation to a kayak-trip (inflatable canoe) on the rivers dades, draa, ahansel and melloul ? I had heard some things different in account of to less water because of to less snowmelt, some other people told me, there are a lot of water and difficulties in the river Melloul (stones, weirs). So i´m not sure, which river I should choose….I have some experiences in white-water, but first and foremost I want to make a relaxed tour without to much sports….Thanx forward
